Question

polyatomic ions

1. no₃⁻ →
2. so₄²⁻ →
3. co₃²⁻ →
4. oh⁻ →
5. nh₄⁺ →

Explanation:

These are common polyatomic ions. The naming of polyatomic ions often has specific rules. For example, "-ate" endings are common for some oxy - anions.

• For \(NO_{3}^{-}\), it is called nitrate ion.
• \(SO_{4}^{2 - }\) is sulfate ion.
• \(CO_{3}^{2 - }\) is carbonate ion.
• \(OH^{-}\) is hydroxide ion.
• \(NH_{4}^{+}\) is ammonium ion.

Answer:

1. nitrate ion
2. sulfate ion
3. carbonate ion
4. hydroxide ion
5. ammonium ion
